SPARK-3178 setting SPARK_WORKER_MEMORY to a value without a label (m or g)
sets the worker memory limit to zero
Validate the memory is greater than zero when set from the
SPARK_WORKER_MEMORY environment variable or command line without a g or m
label. Added unit tests. If memory is 0 an IllegalStateException is thrown.
Updated unit tests to mock environment variables by subclassing SparkConf (tip
provided by Josh Rosen). Updated WorkerArguments to use SparkConf.getenv
instead of System.getenv for reading the SPARK_WORKER_MEMORY environment
variable.
